“…remember eBay? Remember how dozens of competitors tried to get into the eBay space? (and still are?)”

“Why aren’t they succeeding? Because eBay is NOT about the technology. It’s about the community and unless you have something that’ll convince the buyers and sellers all to switch all at one moment you’ll never be able to take eBay’s market away. Translation: it’s too late and eBay has huge defensibility around its business because people won’t move away from it even if you demonstrate 5x better technology.”
